im hoping someone can help me with a simil;ar problem . i had some solution from when i did 2 kilos of mixed ic chips. the solution was a dark mess which i couldnt do anything with , so i dropped what i hope was gold by using copper.
then i put the black silt into AR . i was extremely delighted when my AR turned a lovely dark orange and when tested with stannous , it immidiately gave a solid black result, i thought wow it must be really concentrated with gold. i have had issues precipitating for years tho , its the final stage of gold recovery that i always have problems with . so i plled out my tiny 250 ml beakers to try several different attempts at dropping gold.
in one beaker i put distilled water on heat and added iron sulfate . i left it on heat for about 10 minutes to try and disolve the powder , once disolved i put hcl to make it go green as id seen on videos . also hokes book talks about adding hcl to iron sulfate.when i poured the iron sulfate solution into the sample of AR , it turned brown and hasnt changed , nothing dropped.
in a second beaker i put AR to almost the top and added smb powder. i kept getting what i thought was either red or brown bubbles . as id never heard of red bubbles , i assumed it must be gold dropping then redisolving. which puzzles me as i had used urea untill no more reaction and there was even a little bit that wouldnt disolve . so i thought how could there possibly be any free nitric.
in a third beaker i put a small amount of AR then added smb which was disolved in water first and warmed up to help disolve . once i added it to the solution it went deep red.
im totally lost , i have no idea why or how it can turn red.
i still have half a coffee pot of the AR , which by the way turned light green after i diluted it to twice its volume and added urea.
what should i do with the remaining solution ?
i would really appreciate your help guys
